HOT WATER BOTTLE THERMOMETER Application led April 10,

This invention relates to improvements in hot water bottles. and more particularly to means for combining thermometers therewith.

The objects of the invention are to introduce thermometers into the structure of iieX- ible hot water bottles, douche bags and the like, to show the temperature of the contents and minimize the dangers incident to the 1o external application of hot water bottles too hot, and internal douches, enemas and iiushings, too hot or too cold as the case may be.

Other objects and advantages will appear as this description progresses.

In this specication and the accompanying drawings, the invention-is disclosed in its preferred form, but it is to be understood that it is not limited to such form, because it may be embodied in other forms. It is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.

In the one sheet of drawings:

Figure l is a front elevation of a hot water bottle having a thermometer combined therewith in accordance with this invention.

Figure 2 is an enlarged detail in longitudinal section, adjacent the thermometer, of the same.

Figure 3 is a similar view of a modified form of the same.

Figure 4 is a diagrammatic front elevation of a douche bag modified in accordance with this invention.

In detail the construction illustrated in the drawings referring to Figure 1. comprises the hot water bag 1, having the hanger 2 and the filling funnel 8, in the usual manner. The recess 5 is formed in the side of the bag to receive and protect the thermometer.

The structure of this recess is shown in Figure 2. lts rear wall 6 is an integrally thickened cross section of the wall 1. with the offset wall 7 formin, T the end of the recess. This end wall 7 is carried above the plane of the wall l and has the side walls or shrouds 7 tapering back to the plane of the wall 1, to form the recess 1928. Serial No. 268,910.

The continuation 8, of the wall 7, tapers back to the plane of the wall 1 in the opposite direction. These gradually thickened walls adjacent the recess 5 prevent bending of the structure adjacent the recess at any angle dangerous to the thermometer.

The thermometer structure shown in Figure 2, comprises the protective tubular shell 8, having a tapered portion passing through a hole through the wall 7. The thermometer tube 9 is sealed within the shell 8, which is perforated at 10, to permit access of the contents of the bag to the bulb of the thermometer. The flange 11, cooperating with the said tapered portion, prevents leakage of 55 the contents at this point. This simplified application of the thermometer is suiiicient in suspended douche bags.

The preferred form shown in Figure 3, is capable of withstanding rougher usage, such as hot water bottles and portable apparatus is subjected to.

It comprises the wall 1 thickened at 15 and 16, as previously described, to form the external recess for the thermometer. rlhe threaded bushing 17 is vulcanized into the walls 15-16 and forms the end of the recess.

The thermometer shell 18 is threaded to screw into the bushing 17 and flanged to form a hermetic seal at this point. The thermomau eter tube 19 is sealed into the shell 18, which is perforated, as at the end 19 to permit contact of the thermometer bulb with the contents of the bag,

The douche bag 20 shown in Figure 4, has a5 the outlet 21 and the filler funnel 22. The recess 23, receives the thermometer 24 in the manner suggested in either Figure 2 or Figure 3.

Having thus described this invention what a0 is claimed and desired to secure by Letters Patent is:

1. A fiexible container having a thickened wall at one portion thereof, said thickened wall being distorted to form a recess capable of maintaining its formation, a thermometer positioned in said recess and said thickcned wall having an aperture therethrough through which the bulb of said thermometer projects. 3G@

2. A liexible container having a thickened'l wall at one portion thereof, said thickened wall being distorted to forma recess capable of maintaining its formation, said thickened Wall having an aperture therethrough, a shell having one end projecting through said a erture to the interior of the iexible container and a thermometer located in said shell so that the bulb thereof is situated in the portion of said shell located at the interior of the container.

3. A exible container having a thickened Wall at one portion thereof, s aid thickened f Wall being distorted to form a recess capable of maintaining its formation, said thickened wall having an aperture therethrough, a shell located in said recess and having one end extendin through said aperture to the interior o the container, said portion of ythe shell located upon the interior ofthe container having apertures therein and a thermometer located in said shell so that the bulb thereof is located in that portion of the shell projecting into the container.

4. A flexible container having an external recess, the wall of said container being inteally thickened adjacent said recess; a bush- 1ng in said wall; a thermometer in said recess havin a portion fixed in said bushing and exten ing into said container.

In testimony whereof I have hereunto set my hand this 16th day of March, A. D. 1928.
